Functionality:

- Acquiring another Skaven faction's settlement without any undercity main building under it as Skaven will result in the vanilla behavior. (Thanks to @Otter Disaster for pointing this out)

- On the other hand, If you have an undercity main building under it, acquiring the settlement by any means will choose either city conversion or vanilla behavior, depending on which grants the higher settlement level.

ex: if you confederate Throt, who owns a level 5 Hellpit, even if you had a level 3 Undercity main building in Hellpit, you'll get the level 5 Hellpit, since it’s the highest level between the two.

UI:

- Added an effect description to all Undercity main buildings (level 2 and above) to reflect their Undercity conversion capabilities.

- Fixed a game crash bringed by the 6.1 update
- Updated for 6.1

Hotfix: All Skaven corruption increase/decrease from the food gauge has been set to affect "all provinces". Thank you @JoHein for pointing that out.

UI update:
- Added the High/Low food gauge food consumption/production effect to the Food calculation UI so you can now forsee it's impact
- Added the High skaven corruption food consumption effect to the Food calculation UI, you can now forsee it's impact
- Added an effect scope precision on High/Low food consumption effect to the skaven corruption UI : High/Low Skaven corruption consume/produce food for each owned region in the province.

Balance update:
- Owned regions with low skaven corruption now produce food just like in vanilla.
- The edict "Feed on the weak" now remove 10 corruption and produce one food per owned settlement in the province (its effectiveness is proportional to the province size).
- The edict "Breed, fast, yes yes" is replaced with "Spread Corruption" and consume four foods to spread 8 skaven corruption to adjacent regions (a niche use to get "Menace from bellow" uses and reduce neighbours control).

Note: 100 Skaven corruption in a 4 settlement province cost 20 Food per turn. A huge cost in exchange for a +50% income to all building (as all skaven building produce gold, it can be very strong in a developed province), Nonetheless I find it fair for now as the skavens have multiple ways to get food (undercities, low skaven corruption regions, raiding, etc...).
If you can't stand the high corruption because your food production doesn't follow up, you can use the "Feed on the weak" province edict that massively reduce skaven corruption.

- Fixed a bug when using raze/expand under-empire on a place that already had an under empire cause it have 2 additional build slots that are half-covered by ui. (thanks to 27novuseyu for pointing that out)
- Changed various script elements to make the undercity conversion mechanic multiplayer-friendly
=> I invite anyone that can try skavendom in multiplayer to do so, and report if they get any crash cause by skavendom.

- Warp-Token Stash and Warp-Token Mint buildings income increased. Adjacent income% removed
- Warpstone Refinery Adjacent growth increased, Adjacent income% added
- Subterranean Pit & Mineshafts give chance to expand the under-empire to adjacent provinces like in vanilla.
- Warpstone strip-mind warpbombs increased from 1 to 3
- Lowered some constructions times.
- Buffed all edicts.

Undercity settlements building's food cost are divided by 2 as marauderB proposed : 5+10+20+30 = 65 food total (which is more fair).

Undercity settlements building's construction times have been changed : 1+1+1+2+3 = 8 turns total, to compensate building time of military buildings after converting it.

- Raze & Expand occupation option appear even when you already have an undercity. Changed the script to not attempt to add another undercity if there is already one. It act as a regular "Raze" in that case

- Fixed food consumption and production from the food gauge being “all armies” instead of “all provinces”. Adjusted the values in consequences (see screenshot)

- Added Leadership + and - to food gauge.

New - Raze & Expand Under-Empire: There is a new post-battle option for all skaven faction to Raze and Expand the Under-Empire. All occupation decisions loot values have been updated to reward aggressivity.
